Why is the mouse population changing over time?

• The light mice can reproduce more successfully than the dark mice

• The hawks eat more dark mice than light mice because the dark mice taste better

• The hawks eat more light mice than dark mice because they can see the light mice more easily

• The hawks eat more dark mice than light mice because they can see the dark mice more easily

According to natural selection, organisms more suited to their environment are better able to

• Sleep

• Survive

• Perish

• Migrate

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

1. The process of choosing parent organisms for desired characteristics is called

• natural selection

• Artificial selection

• random selection

• genetic manipulation

What is an example of artificial selection?

• Letting dogs choose their own mate

• Letting plants pollinate on their own

• Crossing a labrador and a poodle to create a labradoodle

Artificial selection is also known as

• natural selection

• selective hearing

• genetic manipulation

• selective breeding

When humans select desirable traits to be passed down to offspring

• natural selection

• artificial selection

Artificial Selection decreases diversity which is bad because

• organisms with same traits will refuse to reproduce with each other

• organisms with all the same traits are susceptible to extinction.

• organisms with the same traits will be very aggressive

• organisms with same traits collectively get smarter and will some day rule the world
